The Microsoft 365 admin center has the option, Let group owners add people outside of your organization to Microsoft 365 Groups as guests. This option can be unchecked to prevent owners from adding guests to their respective teams and groups.
ShareGate Apricot must ignore this global setting or it will supersede the settings on individual teams and groups.
- If the option is unchecked in your global settings, the app will be unable to allow guest access to any group.
- If the option is checked in your global settings, you can block guest access in a team or group's settings.
If you want to be able to control your guest access settings at a team or group level, you can change the global setting in your admin center with the steps in this article from Microsoft.
